Answer:

1. Force = mass x acceleration - Newton

2. A planet moves faster in the part of its orbit nearer the Sun and slower when farther from the Sun, sweeping out  equal areas in equal times - Kepler

3. For any force, there is an equal and opposite reaction force - Newton .

4. An object moves at constant velocity if there is no net force acting upon it - Newton

5. The orbit of each planet about the Sun is an ellipse with the Sun at one focus  - Kepler.

6. More distant planets orbit the Sun at slower average speeds, obeying the precise mathematical relationship p2-a3 - Kepler.

Explanation:

The three laws of planetary motion formulated by Johannes Kepler or Kepler's laws of planetary motion:

  1. The first law states that the planets move around the Sun in an elliptical orbit with the Sun at one of the foci.
  2. The second law states that the line segment joining a planet to the Sun sweeps out equal areas in equal time.
  3. The third law states that the square of the orbital period (p) of a planet is directly proportional to the cube of the mean distance (a) from the Sun (or semi-major axis of its orbit) i.e., p² is proportional to a³.

The three laws of motion formulated by Sir Isaac Newton or Newton's laws of motion:

  1. The first law, also known as the law of inertia states that an object at rest or moves at a constant velocity will remain at rest or keep moving at a constant velocity unless it is acted upon by a force.
  2. The second law states that the total force (F) applied on an object is directly related to the acceleration (a) of that object produced by the applied force and the mass (m) of the object, i.e., F = ma (assuming the mass m is constant).
  3. The third law, also known as the law of action and reaction states that when an object exerts a force on another object, then the latter exerts a force equal in magnitude and opposite in direction on the former object i.e., for every action, there is an equal and opposite reaction. The example includes the recoiling of a gun when it fires a bullet forward.

Ultrasound with a frequency of 4.077 mhz can be used to produce images of the human body. if the speed of sound in the body is t
mestny [16]
The frequency of the ultrasound is (converting in Hz)
f=4.077 MHz=4.077 \cdot 10^6 Hz
while the speed of sound in the body is
v=2.31 km/s = 2310 m/s

We can calculate the wavelength of the ultrasound in the body by using the relationship betwen frequency, wavelength and speed of the wave:
\lambda =  \frac{v}{f}= \frac{2310 m/s}{4.077 \cdot 10^6 Hz}=5.67 \cdot 10^{-4} m

Lenses are often coated with magnesium fluoride (refractive index n = 1.38) to reduce reflections. How thick should the layer of
Valentin [98]

Answer: 99.64 nm (≅ 100 nm)

Explanation: In order to explain this problem we have to obtain destructive inteference from two waves that reflect in the film and lens surface so both waves have a λ/2 shift then we have to get a difference path (2L) equal to an odd number of the half wavelegth.

Then we have the following expression:

L=(m+1/2)* λ/(2*n2);  where n2 is the refractive index of the coating

for m=0 we have the minimum thickness for the coating

L=λ/(4*n2)=99.64 nm (≅ 100 nm)

What is kinematics?<br><br>explain ~​
zhenek [66]
Kinematic equations are the equations that help to describe the motion of an object in constant acceleration. There are 4 of them and they are used in problems regarding motion when the variables are presented in them.

Ex:

Use V=Vo + at if you need to find velocity, and acceleration, time, and Vo are given to you
